    Safety caution

    Warnings on refrigerant leakageCheck of Concentration LimitThe room in which the air conditioner is to be installed requires a design that in the event of refrigerant gas leaking out, its concentration will not exceed a set limit.The refrigerant R410A which is used in the air conditioner is safe, without the toxicity or combustibility of ammonia, and is not restricted by laws to be imposed which protect the ozone layer. However, since it contains more than air, it poses the risk of suffocation if its concentration should rise excessively. Suffocation from leakage of R410A is almost non-existent. With the recent increase in the number of high concentration buildings, however, the installation of multi air conditioner systems is on the increase because of the need for effective use of floor space, individual control, energy conservation by curtailing heat and carrying power etc. Most importantly, the multi air conditioner system is able to replenish a large amount of refrigerant compared with conventional individual air conditioners. If a single unit of the multi conditioner system is to be installed in a small room, select a suitable model and installation procedure so that if the refrigerant accidentally leaks out, its concentration does not reach the limit (and in the event of an emergency, measures can be made before injury can occur). In a room where the concentration may exceed the limit, create an opening with adjacent rooms, or install mechanical ventilation combined with a gas leak detection device.The concentration is as given below.

    Concentration limitCompliance to the local applicable regulations and standards for the concentration limit is required.

    NOTE 1 :If there are 2 or more refrigerating systems in a single refrigerating device, the amounts of refrigerant should be as charged in each independent device.

    For the amount of charge in this example:The possible amount of leaked refrigerant gas in rooms A, B and C is 22 lbs (10 kg).The possible amount of leaked refrigerant gas in rooms D, E and F is 33 lbs (15 kg).

    NOTE 2 :The standards for minimum room volume are as follows.(1) No partition (shaded portion)

    (2) When there is an effective opening with the adjacent room for ventilation of leaking refrigerant gas (opening without a door, or an opening 0.15 % or larger than the respective floor spaces at the top or bottom of the door).

    (3) If an indoor unit is installed in each partitioned room and the refrigerant piping is interconnected, the smallest room of course becomes the object. But when a mechanical ventilation is installed interlocked with a gas leakage detector in the smallest room where the density limit is exceeded, the volume of the next smallest room becomes the object.

    2-1. Selection flow chart (1) Determination of indoor air-conditioning load at each room.

    (2) Preliminary selection of indoor units in the standard capacity no less than air-conditioning load at each room.

    (3) Calculate corrected capacity A of each indoor unit by correcting of indoor temperature for the standard capacity of each indoor unit.([Chart 1])

    (4) Preliminary selection of outdoor unit in the standard capacity no less than total values of corrected capacity A in indoor units. At the same time, check both connectable indoor units number and the outdoor unit diversity(Connected ratio of indoor units to outdoor units) for the specifications.

    (5) Calculate corrected capacity B of each indoor unit by following 2 steps. Step1:Find the correction value of "Connecting pipe length and lift" by both the longest length and the largest height with selected piping condition at (4) or (4)'. ([Chart 3]) Step2:Calculate capacity B by multiplying the value of step1 by corrected capacity A.

    (6) Corrected capacity B of indoor unit >= air-conditioning load (for Allrooms)

    (9) Corrected capacity C of indoor unit >= air-conditioning load (for Allrooms)

    (7) Find correction values of below items for the standard capacity of outdoor unit selected at (4) or (4)'. Then determination of total corrected capacity of the selected outdoor unit by all multiplying. -Correction of indoor temperature condition ([Chart 1]) -Correction of outdoor temperature condition ([Chart 2]) -Correction of connecting pipe length and lift between indoor and outdoor units by both the longest length and the largest height ([Chart 3]) -Correction of outdoor unit diversity in only over 100 % ([Chart 4]) -Correction of frost condition on outdoor heat exchanger when in heating([Chart 5])

    (8) Calculate corrected capacity C of each indoor unit by multiplying the total corrected capacity of outdoor unit at (7) by proportional division of each indoor unit standard capacity for total standard capacity of all indoor units.

    (4)' Increase of outdoor unit capacity.At the same time, check both connectable indoor units number and the outdoor unit diversity

    (5)' The correction characteristic of "connecting pipe length and lift" ([Chart 3]) between increased outdoor unit at (4)' and preliminary selected outdoor unit at (4) is different.(The both graphs aredifferent.)

    2-2. Combination conditions for indoor unit and outdoor unit

    2-2-1. The capacity code for indoor unit, the capacity code is decided for each capacity rank.

    2-2-2. The capacity codes of outdoor units are decided at each capacity type. The maximum number of connectable indoor units and the total value of capacity codes of the indoor units are also decided.

    NOTECompared with the capacity code of the outdoor unit, the total value of capacity codes of the connectable indoor units differs based on the height difference between the indoor units.

    When the height difference between the indoor units is 49 ft (15 m) or lessIf Medium Static Ducted Type (MMD-AP***BH) is excluded in the system: Total indoor capacity code is between 80 % and 125 % of the capacity of the outdoor unit.If Medium Static Ducted Type (MMD-AP***BH) is included in the system: Total indoor capacity code is between 80 % and 120 % of the capacity of the outdoor unit.When the height difference between the indoor units is over 49 ft (15 m)Total indoor unit capacity code (Equivalent to Capacity) is between 80 % and 105 % of the capacity of the outdoor unit.

    After the system has been vacuumed, replace the vacuum pump with a refrigerant cylinder and system with additional refrigerant.

    Refrigerant in the system when shipped from the factory

    When the system is charged with refrigerant at the factory, the amount of refrigerant needed for the pipes at the site is not included. Therefore, calculate the additional amount needed and add the required amount to the system.(Calculation of Heat recovery)Additional refrigerant charge amount is calculated based on the size of liquid pipe at site and its real length.

All field wiring insulation rating must comply with NEC and local codes. All wiring must be strained relieved as specified by NEC and local codes. Do not energize the indoor units until leak check and vacuuming are completed. Use copper supply wire. Use UL wires rated 600 V for the system interconnection wires. Use UL wires rated 300 V for remote control wires.

    4-4. Design of control wiringSummary of control wiring

    1. All system interconnecting and central control wiring should be 2 conductor shielded cable.2. On the header unit the control wire shield and the central control wire shield should both be connected to the

    same ground screw in the header unit.3. The remote control wiring can be 2 conductor un-shielded cable.4. All system interconnecting and control wiring should be sized per table 1, 2 and 3.5. Control wire and power line wire between FS unit and indoor unit are the accessory parts of FS unit. (Wire length

    : 20 ft (6 m))If the length between indoor unit and FS unit exceeds 16 ft (5 m), connect by using the connection cable kit sold separately (RBC-CBK15FUL).
